Here's the symptom, if I idle for too long, the idle eventually tapers off and the bike dies. I can then restart it, but it takes extra throttle to keep it alive. At 40mph+ the bike is fine, behaves like normal. I believed this to be a vacuum leak, ie, at low revs there isn't enough vacuum being generated to pull sufficient gas from the petcock, but some other symptoms cames up...

When the bike is slowly dieing at idle, the carbs are dumping LOTS of gas... I experimented by turning the petcock to "OFF", and running off the gas in the float bowl, and it runs fine (until the float bowls are emptied I guess). Anyway, I think I've determined that the problem is a sticky float valve, causing the carbs to always want more gas, even if they're full up already, which explains the fuel dumping when the carbs don't actually need more gas, ie, idle. The bike runs excellently on the freeway.

What do you guys think? I saw a similar case mentioned elsewhere, but I think this deserves its own thread.

Bingo! now your thinking. The carbs are flooding.
